Truong Duc Kien created FLINK-8949:
--------------------------------------
Summary: Rest API failure with long URL
Key: FLINK-8949
URL: https://issues.apache.org/jira/browse/FLINK-8949
Project: Flink
Issue Type: Bug
Components: REST, Webfrontend
Affects Versions: 1.4.2
Reporter: Truong Duc Kien
When you have jobs with high parallelism, the URL for a REST request can get
very long. When the URL is longer than 4096 bytes, the REST API will return
error
{{Failure: 404 Not Found}}
This can easily be seen in the Web UI, when Flink queries for the watermark
using the REST API:
{{GET
/jobs/:jobId/vertices/:vertexId/metrics?get=0.currentLowWatermark,1.currentLowWatermark,2.currentLo...}}
The request will fail with more than 170 subtasks and the watermark will not be
displayed in the Web UI.
